SOUTH BURLINGTON — The South Burlington Development Review Board has voted to uphold a permit for a proposed methadone clinic for heroin and prescription drug addicts.

The board voted 4-2 on Friday to deny an appeal from the school district, which argued that the facility could bring crime and traffic to the proposed site near the city’s high school and middle school.

The HowardCenter wants to open the clinic as soon as possible to serve more than 650 clients.

The center would close two other smaller clinics in Burlington and South Burlington.
